AI总结:

本文利用 SPT-3G 前两年 CMB 温度图测量 DES Y3 redMaPPer 星系团的叠加透镜信号,校准三类样本的平均质量,精度较前代 SPT 提升约2倍,并预测完整巡天可达5.7%约束。

摘要:

我们利用来自 SPT-3G 的宇宙微波背景(CMB)温度数据,测量了 Dark Energy Survey Year 3(DES Y3)redMaPPer 样本中星系团方向上的叠加透镜信号;SPT-3G 是南极望远镜(South Pole Telescope,SPT)上的第三代 CMB 相机。我们使用由 SPT-3G“Main”巡天最初2年数据构建的温度图来估计透镜信号,这些数据覆盖南天1500 deg²。随后,我们将该信号用作 DES 样本平均星系团质量的代理量。在本研究中,我们采用三个版本的 redMaPPer 星表:包含8865个星系团的 Flux-Limited 样本、包含5391个星系团的 Volume-Limited 样本,以及包含4450个星系团的 Volume&Redshift-Limited 样本。对于这三个样本,我们得到的平均星系团质量分别为 M_200m = 1.66±0.13 [统计]±0.03 [系统]、1.97±0.18 [统计]±0.05 [系统] 和 2.11±0.20 [统计]±0.05 [系统] ×10^14 M_⊙。相对于以往几代 SPT 巡天的测量精度,这提升了约2倍,并且是迄今为止利用 CMB 星系团透镜效应获得的最具约束力的星系团质量测量。总体而言,我们发现本文结果与以往研究给出的 redMaPPer 质量-富度度标关系所得质量之间不存在显著张力;这些关系曾利用 CMB 星系团透镜、光学弱透镜以及来自 DES、SDSS 和 Planck 数据各种组合的速度弥散测量进行校准。随后,我们将样本划分为3个红移区间和3个富度区间,发现在这些区间内与经光学弱透镜校准的质量没有显著张力。我们预测,在使用完整 SPT-3G 巡天、同时利用温度和偏振数据,并纳入来自“Extended” SPT-3G 巡天额外约1400 deg²的观测时,对 DES Y3 样本平均星系团质量的约束可达到5.7%。

英文摘要:

We measure the stacked lensing signal in the direction of galaxy clusters in the Dark Energy Survey Year 3 (DES Y3) redMaPPer sample, using cosmic microwave background (CMB) temperature data from SPT-3G, the third-generation CMB camera on the South Pole Telescope (SPT). We estimate the lensing signal using temperature maps constructed from the initial 2 years of data from the SPT-3G 'Main' survey, covering 1500 deg$^2$ of the Southern sky. We then use this signal as a proxy for the mean cluster mass of the DES sample. In this work, we employ three versions of the redMaPPer catalogue: a Flux-Limited sample containing 8865 clusters, a Volume-Limited sample with 5391 clusters, and a Volume&Redshift-Limited sample with 4450 clusters. For the three samples, we find the mean cluster masses to be ${M}_{200{\rm{m}}}=1.66\pm0.13$ [stat.]$\pm0.03$ [sys.], $1.97\pm0.18$ [stat.]$\pm0.05$ [sys.], and $2.11\pm0.20$ [stat.]$\pm0.05$ [sys.]$\times{10}^{14}\ {\rm{M}}_{\odot }$, respectively. This is a factor of $\sim2$ improvement relative to the precision of measurements with previous generations of SPT surveys and the most constraining cluster mass measurements using CMB cluster lensing to date. Overall, we find no significant tensions between our results and masses given by redMaPPer mass-richness scaling relations of previous works, which were calibrated using CMB cluster lensing, optical weak lensing, and velocity dispersion measurements from various combinations of DES, SDSS and Planck data. We then divide our sample into 3 redshift and 3 richness bins, finding no significant tensions with optical weak-lensing calibrated masses in these bins. We forecast a $5.7\%$ constraint on the mean cluster mass of the DES Y3 sample with the complete SPT-3G surveys when using both temperature and polarization data and including an additional $\sim1400$ deg$^2$ of observations from the 'Extended' SPT-3G survey.
